Description

Technical Field

[0001] The utility model relates to the technical field of underground continuous wall construction, in particular to an I-beam joint scraping and brushing multifunctional wall brush for underground continuous walls. Background Art

[0002] When the underground continuous wall is trenched, in order to ensure that the steel cage with I-beam joints is smoothly lowered into the construction trench section, the grab bucket extends outward by about 70 centimeters at both ends of the trench section when excavating the trench section. Before pouring the wall concrete, sandbags are filled at the over-excavated I-beam joints on both sides to prevent seepage when pouring concrete. However, in the actual construction process, concrete will inevitably seep into the adjacent trench section and stick to the I-beam joints. For this reason, when constructing adjacent trench sections, the I-beam joints need to be brushed in advance, and a wall brusher is used for the brushing treatment.

[0003] The existing wall brush adopts the impact-type wall brushing method. The quality and efficiency of cleaning the I-beam joints of the underground continuous wall directly affect the water-stopping effect and construction progress of the underground continuous wall. When the wire brush encounters irregularly distributed concrete blocks in the impact-type wall brushing method, the suspended wall brush is prone to sliding along the layer. When encountering concrete with a certain strength, the brushing force is insufficient, and there are problems such as poor wall brushing effect and difficulty in verticality control. As a result, wall brushing takes a long time and has reduced efficiency, which increases the overall construction cost and brings inconvenience to people's use. Therefore, a multifunctional wall brush for scraping and brushing the I-beam joints of underground continuous walls has been introduced in a targeted manner. Summary of the invention

[0004] The utility model aims to provide a multifunctional wall brush for scraping and brushing I-beam joints of underground continuous walls, which has the advantages of high wall brushing efficiency, good wall brushing effect and low wall brushing cost, and solves the problem that the existing multifunctional wall brush adopts an impact-type wall brushing method, and the quality of the wall brushing of the I-beam joints of the underground continuous wall and the cleaning efficiency directly affect the water-stopping effect and construction progress of the underground continuous wall. In the impact-type wall brushing method, when the wire brush encounters irregularly distributed concrete blocks, the suspended wall brush is prone to sliding along the layer. When encountering concrete with a certain strength, the brushing force is insufficient, and there are problems such as poor wall brushing effect and difficulty in verticality control, which results in a long time-consuming wall brushing, reduced efficiency, increased overall construction costs, and inconvenience for people's use.

The bucket teeth 8 are used to brush the wall first. When brushing the wall, the bucket teeth 8 are close to the I-beam at the groove section mouth, and along the I-beam joint from top to bottom. When encountering concrete blocks, the bucket teeth 8 are used to scrape the concrete blocks on the I-beam surface. Due to the influence of the spacing of the bucket teeth 8, strip-shaped concrete blocks are left on the I-beam. After the bucket teeth 8 are finished brushing the wall, the wall brusher is taken out of the groove The rotary drilling rig turns the direction of the wall brush, and then uses one side of the wire brush 7 to clean the strip concrete blocks remaining after scraping the wall. By adopting the universal joint square tube 1 of the rotary drilling rig, the installation and disassembly are fast and convenient, the lifting and lowering operations of the rotary drilling rig are fast, and the wall brushing frequency is high.
